,-Beit known that I, EDWIN E. MANTEa, a .-.ycitizen of the United States,

residing at Au- Vburndalejn the county of Middlesex and State `,ollltiassachusetts,haveinven ted new and use- 1- p lful Improvements in Sliding Doors, of which .theffollowiug is a specification.

.My invention has relation to improvements p insliding doors of that kind or class wherein,` :N121` hing'edntogether and arranged to slide or [the door comprises vertical panels or secti ons travterse on curved or deflected tracks or guiderails; and-the object is to provide such a 'door t with hangers and supports of simplified con- ,"5 n `in operation. I. y

struction and which-are.. eicient and certain The invention embodies"hanger-brackets, rollers journaled in the brackets, upper and lower curved guide-rails. engaged by the bracketsand rollers, Iand improved means for ,carryingand guiding thelower end of the door in alinement with the upper end, all as will be hereinafter fully described and the' r novelty thereof particularly pointed out and "designed for and adapted toV :distinctly claimed.`

is particularly car doors ar- The invention as illustrated ranged in vestibule constructions mounted ron the platforms of cars; but it is apparent that itmaybeadapted to similar constructions wherever it is desirable 'to slide a door `4on curved or deiiected tracks.

*35, r l `similarv reference designations .indicate the `I have fully and clearlyillustrated my invention in the annexed drawings, to be taken asfa part of this specification, and wherein saine parts appearing in the respective illustrationsf' and reference being made to the drawings. c

Ilgu're 1 is aefront View of a door con-u structed'in accordance with my invention and,

into which `the door slides;

a sideA end view in elevation of a vestibule" In this view the door'is made up of two panels hinged together.` Fig. 2 is a view identical to Fig. l, except that the door is shown as consisting of three pan` els hinged together. Fig. 3 is a view in lon'- gitudinal section through the vestibule-walls -and plan view of a portion of the platform,

showing the door as consisting of two panels and moved into the vestibule. Fig. 4 is. a view similar to Fig. 3, except that the door lment-with the spective View of one of the supports of 'the hangers fixed to the upper-end ofjthe door.

is niade up of three panels. tical sectional View of one of rollers, tive position relative to theguide-rails. Fig. 6 isa front view in elevation o'f the hangers` as inoperative 'position on the guide-rails or tracks: Fig. 7 is a fragmentary end vievv'of-A two sections of thedoor, showing the hingeconnection, and thejacent to the hinge. elevation showing the hin'ge connection, the guide-rails, andthe guide-block in engagep 4 lower edge of the lower guiderail. Fig. 9 is a detail vertical section of one the hangers and.I

of the guide-block socket-pieces with the stein of the guide-block in the socket and the rail in the head of the block.l Fig. l is a per Fig. 1l' is a detail transverse vertical view of the track in which thelower'end of the door slides. A l

As mentioned, the invention is particularly. illustra-ted as -applied to a ,can-and' reference being had to the drawings, Adesignates the end portion of the floor of a car having end walls 1 2, with a door-space between them, the wall 2 being shown as constructed to takein a sliding door in a well-known -lnannekr B designates the platform o a car, on` the oor of which along the edge are secured ribs o'r cleats 3, in which the lower end-of the door moves. I prefer 4to-make `these ribs integral with a base -plate 4, with flanges through which fastening-screws may be projected to secure it in position. -Wooden angle-strips may be laid and secured beside the ribs to prevent them from undue wear and to present a more agreeable tread-surface.

designates the vestibule wall, reaching jacross the4 front of the platform-and pro-4 showing their arrangement in. opera-"'.

6o l guide-block arranged'ad- Fig. 8 is a detail front vided with panes of glass 6,.,as usual, `as seen at Fig. 1 of the drawings, lor if the vestibule is erected in' other structures itvmaytbe solidr` 4throughout'its height, as shown in` Fig. 2 of the drawings. The corners of the vestibule are made rounded, as shown, and the walls at this part made double, with a space between them suicient in capacity and transverse depth to take and contain the door, as indicated in Figs. 2 and 3e The inner curved wall at its inner edge is connected and secured to the main wall, and at the outer end the walls are so'spaced as to permit the door 4so the knuckles dov not project beyond the face ofthe panels of the door, thus providing al .plain and straight surface to the door.

Above the door and extending in curved di- `I rection within the door-space in the rounded 2o 'cured a metal bar 10formed with a longituends of the vestibule 4is secured l a rail 9, to the, upper inner ace ofwhich is suitably sedinal groove 11 in its under side and extending thelength thereof. The rail 9 is provided with a rib 12, tothe face of which is secured the `rail 13, disposed in vertical alinement with the guide-groove 11 and preferably having a rounded tread-surface and reaching vertically a suitable distance below the rib 12 to be engaged by the guide-blocks on the end and preferably at or adjacent to the cor-l end of the door, as shown in the drawings.

To the' inner face of the door, at the upper ners, are secured brackets, consisting of plates 14, formed at their upper ends with a hollow vertical extension 15, having interior screwthreads, the extension constitutinga socketpiece for the purpose hereinafter specified. j E designates brackets constituting' the hangers which sustain the door. These brackets consist of a vertical threaded stem 17, engaging in the socket 15, a vertical arm 18, an overhanging 'or bridge piece 19, and a depending arm 2t 'between which and the arm 18 is journaled the grooved pulley, sheave, or roller 2l, mounted on the arbor 22. The

grooved pulley 2l is seated on and rides upon the rail 13, as indicated in the drawings.

The overhanging bridge-piece is formed with.

a vertically-extending pin or lug 23, which engages in the groove 11 in the striplO. It

will be seen that the hangers are held in vertical position by the engagement of the pulley Vwith the rail and the engagement of the lug 23 in the groove 11. It will also be perceived that the threaded connection of the stem 17 in the socket-piece 15 permits the hangers to have the requisite rotary movement on the axis of the stem 17 to accommodate them to rse,124

the curvature of the track or rail on which the rollers run; also, this threaded connection permits the adjustment of the door to be made relatively to thehangers and `their supports.

In the upper ends of the panels of the door are posited one or more secket-brackets 24, having interior screw-threads and`provided with a lateral extension-plate 25, having holding-screws 26 projected through it into the In the threaded socket is fitted a threaded stem 27, formed with a headpiece 28, having a groove 29 in it, which engages over the lower edge of the rail 13, as shown in the drawings, and assists Yin guiding the door on its Itrack. The threaded connection of the stem 27 and the socket permits the stem to turn on its airis and the head tomove therewith sufficient to allow the head to trav erse the rail without cramping.

What I claimis- 1. The combination, with a sliding' door composed of vertical panels hinged together,

of a hanger comprising a plate secured to the upper end of the door and formed with a vertical socket piece having interior screwthreads, y a hanger bracket formed with a threaded stem to engage the threaded socket, a vertical arm having an overhanging part formed with a vertical guide-lug, and a depending arm, a. grooved pulley journaled between the said arms, a track-rail on which the pulley travels, and a guide-strip formed with a groove in its under side in which the guidelug on the hanger engages.

2. The combination with a sliding door composed of vertical panels hinged together, of hangerseach comprising a plate secured to the upper end of the door and formed with a vertical socket-piece having interior'screwthreads, a hanger-bracket vformed with a threaded stem to engage inV the threaded, socket, avertical arm having an overhanging part formed with a vertical guide-lug and a depending arm, a grooved pulley journaled between said arms, a curved track-rail on which the pulley travels, a curved strip formed with a guidegroove in its under side, and a guide-'block secured to the door'andformed with a groove in its upper face to engage the lower edgeof the track-rail.
